MAINTENANCE INSTRUCTIONS
LOGOSOL’s ripping chain allows quick length sawing
with a thin kerf. But it is less durable than normal
chains. If you keep the cutting equipment in good
condition, you get the right timber dimensions,
faster sawing and the cutting equipment will last
longer.
Sharpen the chain before it gets dull
When the chain is beginning to get dull, you will
notice that the cutting speed is decreasing, the
guide bar becomes hot and it becomes harder
to feed the saw unit forward. Stop sawing
immediately! Acctually, when this happens, it is
already too late to sharpen the chain. Sawing with
a dull chain exposes the cutting equipment to high
levels of mechanical stress. Therefore, sharpen the
chain before it becomes dull!
Avoid chain breaks
If you are sawing too long with a dull chain, it can
break. The chain breaks under the cutting teeth, and
you will see that it is worn there.
If, however, a drive link breaks, this can be due to
the chain and sprocket not being a good match. A
completely new chain on a worn sprocket can break
in the first few minutes of use.
The guide bar can pull askew
If the chain has been damaged on one side or been
filed unevenly, it can run incorrectly. The guide bar is
pressed upwards or downwards and ”springs back”
when it comes out of the log. The chain will then
wear more on one bar rail, and if you continue to
saw the guide bar will wear unevenly. Even though
you replace the chain, an unevenly worn bar can
guide the chain incorrectly and, in addition, the
new chain can also be worn down. An unevenly
worn bar can be repaired. File the bar rails so they
are equally high with an edge file (SKU: 9999-000-
0450) or LOGOSOL’s electric guide bar grinder (SKU:
7804-000-0005).
Another more common reason for the guide bar
pulling askew is that it is worn out so that the drive
links touches the bottom in the track of the guide
bar and the chain loses the support provided by the
bar rails. This is shown on the chain by the tip on
the drive link becoming worn.
The best chain oil
In order for the chain oil to work well it must
be viscous and thready. When you place a drop
between the thumb and the index finger and
then open them, long threads should form. We
recommend LOGOSOL’s sawmill chain oil, SKU
numbers as given below:
1 litre, SKU: 0718-000-1001
10 litres, SKU: 0718-000-1010
Handbook for your cutting tools
LOGOSOL has a separate document which we
keep updated with respect to the technical
specification of the latest new products. It is called
’The Handbook for Your Cutting Tools’ and can be
downloaded free of charge from our web site. You
can also order a printed version.
